About the Whip-poor-will

The whip-poor-will, named for its distinctive call (which sounds
like “whip-poor-will”) is a mottled grayish-brown bird with a long rounded
tail and rounded wings. The males have black throats and a white necklace.
They also have white outer tail feathers. The females have a thinner
necklace and lack the white on the tail.

Like the owl, the whip-poor-will is a night hunter. But while an
owl hunts primarily by sound, the large-eyed whip-poor-will hunts by
sight.
